A conducting rod of length 23 cm lies parallel to the y axis and moves in the x direction with a displacement given by
x(t) = 3.85 cos(485 t) cm,
where t is in seconds to make the argument of the trig function come out in radians. The rod is in a uniform magnetic field of 2.2 T that is in the +z direction. What is the EMF induced in the rod as a function of time? Use a standard sign convention where the EMF is positive when it would make a current flow in the +y direction in the bar.
